Yintoni i-corrosion resistance ye-alloy steel bar round?

Xa kuziwa kwi-corrosion resistance ye-alloy steel bar round bar, uhlobo oluthile lwensimbi esetyenzisiweyo kufuneka luqwalaselwe. Imivalo yentsimbi engqukuva, enje nge-4140 yentsimbi engqukuva bar, 42crmo4 bar yentsimbi engqukuva kunyeaisi 4140 bar yentsimbi engqukuva, ziyaziwa ngamandla azo aphakamileyo kunye nokuqina kwazo. Nangona kunjalo, ukuxhathisa kwabo kwe-corrosion kuya kwahluka ngokuxhomekeke kuhlobo oluthile lwe-alloy kunye nonyango lwangaphandle.
Enye yezinto eziphambili ezibangela ukuxhathisa kwe-corrosion ye-alloy steel bar round bar kubukho bezinto ezithile zokudibanisa. Ngokomzekelo, i-chromium ihlala yongezwa kwii-alloys zentsimbi ukunyusa ukuxhathisa ukubola. Oku kubonakala ngokukodwa kwiintsimbi ezijikelezayo ezingama-4140, eziqulethe izixa ezikhulu zechromium, zibanika ukuxhathisa okugqwesileyo kwe-corrosion. Ukongezelela, kukho ubukho be-molybdenum42crmo4 intsimbi engqukuvayongeza ngakumbi ukuxhathisa kwayo ku-corrosion, iyenze ilungele usetyenziso kwiindawo ezirhabaxa.
Ukongeza kwi-alloy composition, unyango olungaphezulu lweentsimbi zentsimbi ezijikelezileyo nazo zidlala indima ebalulekileyo ekuxhathiseni ukubola. Ibha yentsimbi eyakhiweyo engqukuva iqhuba inkqubo ethile yokuvelisa ukuqhubela phambili nokuphucula ukuxhathisa kwayo kukutya. Ngeenkqubo ezifana nokunyangwa kobushushu kunye nokugquma komhlaba, ukuxhathisa kwe-corrosion yale mivalo yensimbi kuphuculwe kakhulu, okwenza ukuba ifaneleke kwizicelo ezininzi, kubandakanywa neendawo zaselwandle kunye nezoshishino.

Kuyaphawuleka ukuba nangona ibha yentsimbi engqukuva i-alloy inokumelana ne-corrosion, isenokuthi ichaphazeleke kwiindidi ezithile zomhlwa, ngakumbi kwindawo enomhlwa. Ngoko ke, ukugcinwa okufanelekileyo kunye nokuhlolwa rhoqo kubalulekile ukuqinisekisa ukusebenza kwexesha elide le mivalo yensimbi.
Isishwankathelo, ukuxhathisa umhlwa kweingxubevange yentsimbi imivalo ngeenxa zonkenjengentsimbi ye-4140 yentsimbi ejikelezayo, i-42CrMo4 ibha yensimbi ejikelezayo, i-AISI 4140 ibha ejikelezayo, ibha yentsimbi edibeneyo, njl njl. Ngokuqonda le miba kunye nokukhetha ibha yokujikeleza echanekileyo kwisicelo esithile, iinkampani zinokuqinisekisa ukusebenza okuthembekileyo kunye nexesha elide kwiindawo ezinobungozi.
